combine 2 banks into a single mtd device?

Hello,

I am trying to boot from flash on the SC520 development platform from AMD.
>From Vipin I received some code to access the flash. But with this code I get
two devices mtd0 and mtd1 for each flash bank of 8 MB.

Is there a way to combine the two banks into one mtd device of 16MB? So that
I can put a simple Linux system on it.

David is the jffs2 code beta enough for some read only testing?

Thanks for reading sofar.

	Erik

Yep. Whatever map driver you're using, switch the add_mtd_partitions call 
to just register the underlying MTD device directly rather than the 
partitions.

Testing is good, yes please. Read-only testing is pointless because nobody's
written a mkfs.jffs2 yet, so you have to mount an empty filesystem and then
fill it. It seems OK at the moment until you get to the end of the flash 
and the GC starts having to do some work. Compression is working nicely. 

I'm working on the GC code. The scan code and the normal read/write/etc 
operations want exercising. And mkfs.jffs2 wants writing :)
